Abstract: An optical fiber coating die assembly is provided. The optical fiber coating die assembly includes a housing defining a guide chamber having an inlet for receiving optical fiber and an outlet, a guide die located at the outlet of the guide chamber, and a sizing die. The optical fiber coating die assembly also includes a coating applicator disposed between the guide die and the sizing die, and a tube operatively coupled to the inlet of the guide chamber and axially aligned with the chamber to receive the optical fiber fed into the guide chamber and provide a barrier to air flow.

Abstract: A system for processing optical fiber includes a draw furnace, a fiber conveyance pathway extending between an upstream end positioned at the draw furnace and a downstream end positioned opposite the upstream end, where optical fiber is conveyed along the fiber conveyance pathway from the upstream end to the downstream end in a fiber conveyance direction, a muffle in communication with the draw furnace and positioned downstream of the draw furnace, a second cooling device annularly surrounding the fiber conveyance pathway downstream from the draw furnace, the second cooling device including one or more second cooling device heating elements and a first cooling device positioned between the draw furnace and the second cooling device, wherein the first cooling device directs a fluid to contact the optical fiber.

Abstract: The high-density FAU comprises a support substrate having a grooved front-end section that supports glass end sections of the small diameter low-attenuation optical fibers. A cover is disposed on the front-end section and secured thereto to hold the glass end sections in place. The substrate and the cover can be made of the same glass or glasses having about the same CTE. The glass end sections have a diameter d4 so that the pitch P2 of the fibers at the front end of the FAU can be equal to or greater than d4, wherein d4=2r4, with r4 being the radius of the glass end section as defined by the optical fiber cladding. The glass end section has a radius r4 less than 45 microns, allowing for a high-density FAU and a high-density optical interconnection device.

Abstract: An optical fiber comprising: a core having an outer radius ri; a cladding having an outer radius r4 8 microns, the primary coating having in situ modulus EP of 0.35 MPa or less and a spring constant χP 10 microns and r6≤85 microns. The fiber has a mode field diameter MFD greater than 8.2 microns at 1310 nm; a cutoff wavelength of less than 1310 nm; and a bend loss at a wavelength of 1550 nm, when wrapped around a mandrel having a diameter of 10 mm, of less than 1.0 dB/turn.
